We get it, Miley. You're not Hannah Montana anymore. Now put some pants on, young lady! There were plenty of gorgeous looks on the red carpet at 2012 Billboard Music Awards in Las Vegas, but Miley Cyrus stole the show by wearing only a double-breasted -- literally and sartorially -- white tuxedo jacket by Jean-Paul Gaultier ... and nothing else. Wait, does a delicate chain draped down her cleavage and forking below her breasts count? The 19-year-old, who sparked a huge scandal when she posed for Annie Leibovitz in bed while wearing only in a sheet when she was 16 and again when she essentially pole danced at the Teen Choice Awards in 2009, recently told Amanda De Cadenet on her Lifetime show that the public backlash of her increasingly sexual looks comes from fear of not being able to deal with confident women.

White was a popular, if not always successful, look for the evening, with Monica wowing in a long-sleeved jersey dress with deep keyhole neckline. Nelly Furtado wore an overly-complicated white crochet dress with a Dolly Parton-esque collar, her black bra peeping over the top of the neckline. And Amber Rose came thisclose to a wardrobe malfunction in a white textured bustier minidress -- she looked like she was going to bust out of that bustier at any moment.

Jordin Sparks looked elegant yet edgy in a streamlined black leather bustier top with a bright blue skirt. Katy Perry toned it down -- for her -- in a sleek lilac gown that was sequined and subtly studded, her hair now a deep purplish-black. And Taylor Swift stepped it up -- again, for her -- by eschewing her typical princess-y look in a deep pink sleeveless gown with a lace bodice (with nude lining, of course).
